B. Signal transmission/reception method in wireless communication system

2 is a diagram illustrating an example of a method of transmitting/receiving a signal in a wireless communication system.

Referring to FIG. 2, when the UE is powered on or newly enters a cell, the UE performs an initial cell search operation such as synchronizing with the BS (S201). To this end, the UE receives a primary synchronization channel (P-SCH) and a secondary synchronization channel (S-SCH) from the BS, synchronizes with the BS, and obtains information such as cell ID. can do. In the LTE system and the NR system, the P-SCH and S-SCH are referred to as a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), respectively. After initial cell discovery, the UE may obtain intra-cell broadcast information by receiving a physical broadcast channel (PBCH) from the BS. Meanwhile, the UE may check a downlink channel state by receiving a downlink reference signal (DL RS) in the initial cell search step. Upon completion of the initial cell search, the UE acquires more detailed system information by receiving a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH) according to the information carried on the PDCCH. It can be done (S202).

Meanwhile, when accessing the BS for the first time or when there is no radio resource for signal transmission, the UE may perform a random access procedure (RACH) for the BS (steps S203 to S206). To this end, the UE transmits a specific sequence as a preamble through a physical random access channel (PRACH) (S203 and S205), and a random access response to the preamble through the PDCCH and the corresponding PDSCH (random access response, RAR) message can be received (S204 and S206). In the case of contention-based RACH, a contention resolution procedure may be additionally performed.

After performing the above-described process, the UE receives PDCCH/PDSCH (S207) and physical uplink shared channel (PUSCH)/physical uplink control channel as a general uplink/downlink signal transmission process. Uplink control channel, PUCCH) transmission (S208) may be performed. In particular, the UE receives downlink control information (DCI) through the PDCCH. The UE monitors the set of PDCCH candidates from monitoring opportunities set in one or more control element sets (CORESET) on the serving cell according to the corresponding search space configurations. The set of PDCCH candidates to be monitored by the UE is defined in terms of search space sets, and the search space set may be a common search space set or a UE-specific search space set. CORESET consists of a set of (physical) resource blocks with a time duration of 1 to 3 OFDM symbols. The network can configure the UE to have multiple CORESETs. The UE monitors PDCCH candidates in one or more search space sets. Here, monitoring means attempting to decode PDCCH candidate(s) in the search space. If the UE succeeds in decoding one of the PDCCH candidates in the discovery space, the UE determines that the PDCCH is detected in the corresponding PDCCH candidate, and performs PDSCH reception or PUSCH transmission based on the detected DCI in the PDCCH. The PDCCH can be used to schedule DL transmissions on the PDSCH and UL transmissions on the PUSCH. Here, the DCI on the PDCCH is a downlink assignment (ie, downlink grant; DL grant) including at least information on modulation and coding format and resource allocation related to a downlink shared channel, or uplink It includes an uplink grant (UL grant) including modulation and coding format and resource allocation information related to the shared channel.

With reference to FIG. 2, an initial access (IA) procedure in a 5G communication system will be additionally described.

The UE may perform cell search, system information acquisition, beam alignment for initial access, and DL measurement based on the SSB. SSB is used interchangeably with a Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block.

SSB consists of PSS, SSS and PBCH. The SSB is composed of four consecutive OFDM symbols, and PSS, PBCH, SSS/PBCH or PBCH are transmitted for each OFDM symbol. The PSS and SSS are each composed of 1 OFDM symbol and 127 subcarriers, and the PBCH is composed of 3 OFDM symbols and 576 subcarriers.

Cell discovery refers to a process in which the UE acquires time/frequency synchronization of a cell and detects a cell identifier (eg, Physical layer Cell ID, PCI) of the cell. PSS is used to detect a cell ID within a cell ID group, and SSS is used to detect a cell ID group. PBCH is used for SSB (time) index detection and half-frame detection.

There are 336 cell ID groups, and 3 cell IDs exist for each cell ID group. There are a total of 1008 cell IDs. Information on the cell ID group to which the cell ID of the cell belongs is provided/obtained through the SSS of the cell, and information on the cell ID among 336 cells in the cell ID is provided/obtained through the PSS.

SSB is transmitted periodically according to the SSB period. The SSB basic period assumed by the UE during initial cell search is defined as 20 ms. After cell access, the SSB period may be set to one of {5ms, 10ms, 20ms, 40ms, 80ms, 160ms} by the network (eg, BS).

Next, it looks at obtaining system information (SI).

SI is divided into a master information block (MIB) and a plurality of system information blocks (SIB). SI other than MIB may be referred to as RMSI (Remaining Minimum System Information). The MIB includes information/parameters for monitoring the PDCCH that schedules the PDSCH carrying System Information Block1 (SIB1), and is transmitted by the BS through the PBCH of the SSB. SIB1 includes information related to availability and scheduling (eg, transmission period, SI-window size) of the remaining SIBs (hereinafter, SIBx, x is an integer greater than or equal to 2). SIBx is included in the SI message and is transmitted through the PDSCH. Each SI message is transmitted within a periodic time window (ie, SI-window).

Referring to FIG. 2, a random access (RA) process in a 5G communication system will be additionally described.

The random access process is used for various purposes. For example, the random access procedure may be used for initial network access, handover, and UE-triggered UL data transmission. The UE may acquire UL synchronization and UL transmission resources through a random access process. The random access process is divided into a contention-based random access process and a contention free random access process. The detailed procedure for the contention-based random access process is as follows.

The UE may transmit the random access preamble as Msg1 of the random access procedure in the UL through the PRACH. Random access preamble sequences having two different lengths are supported. The long sequence length 839 is applied for subcarrier spacing of 1.25 and 5 kHz, and the short sequence length 139 is applied for subcarrier spacing of 15, 30, 60 and 120 kHz.

When the BS receives the random access preamble from the UE, the BS transmits a random access response (RAR) message (Msg2) to the UE. The PDCCH for scheduling the PDSCH carrying RAR is transmitted after being CRC masked with a random access (RA) radio network temporary identifier (RNTI) (RA-RNTI). A UE that detects a PDCCH masked with RA-RNTI may receive an RAR from a PDSCH scheduled by a DCI carried by the PDCCH. The UE checks whether the preamble transmitted by the UE, that is, random access response information for Msg1, is in the RAR. Whether there is random access information for Msg1 transmitted by the UE may be determined based on whether there is a random access preamble ID for the preamble transmitted by the UE. If there is no response to Msg1, the UE may retransmit the RACH preamble within a predetermined number of times while performing power ramping. The UE calculates the PRACH transmission power for retransmission of the preamble based on the most recent path loss and power ramping counter.

The UE may transmit UL transmission as Msg3 in a random access procedure on an uplink shared channel based on random access response information. Msg3 may include an RRC connection request and a UE identifier. In response to Msg3, the network may send Msg4, which may be treated as a contention resolution message on the DL. By receiving Msg4, the UE can enter the RRC connected state.

C. Beam Management (BM) procedure of 5G communication system

The BM process may be divided into (1) a DL BM process using SSB or CSI-RS and (2) a UL BM process using a sounding reference signal (SRS). In addition, each BM process may include Tx beam sweeping to determine the Tx beam and Rx beam sweeping to determine the Rx beam.

Let's look at the DL BM process using SSB.

Configuration for beam report using SSB is performed when channel state information (CSI)/beam is configured in RRC_CONNECTED.

-The UE receives a CSI-ResourceConfig IE including CSI-SSB-ResourceSetList for SSB resources used for BM from BS. The RRC parameter csi-SSB-ResourceSetList represents a list of SSB resources used for beam management and reporting in one resource set. Here, the SSB resource set may be set to {SSBx1, SSBx2, SSBx3, SSBx4, 쪋}. The SSB index may be defined from 0 to 63.

-The UE receives signals on SSB resources from the BS based on the CSI-SSB-ResourceSetList.

-When the CSI-RS reportConfig related to reporting on SSBRI and reference signal received power (RSRP) is configured, the UE reports the best SSBRI and RSRP corresponding thereto to the BS. For example, when the reportQuantity of the CSI-RS reportConfig IE is set to'ssb-Index-RSRP', the UE reports the best SSBRI and corresponding RSRP to the BS.

When the UE is configured with CSI-RS resources in the same OFDM symbol(s) as the SSB, and'QCL-TypeD' is applicable, the UE is similarly co-located in terms of'QCL-TypeD' where the CSI-RS and SSB are ( quasi co-located, QCL). Here, QCL-TypeD may mean that QCL is performed between antenna ports in terms of a spatial Rx parameter. When the UE receives signals from a plurality of DL antenna ports in a QCL-TypeD relationship, the same reception beam may be applied.

Next, a DL BM process using CSI-RS will be described.

The Rx beam determination (or refinement) process of the UE using CSI-RS and the Tx beam sweeping process of the BS are sequentially described. In the UE's Rx beam determination process, the repetition parameter is set to'ON', and the BS's Tx beam sweeping process is set to'OFF'.

First, a process of determining the Rx beam of the UE will be described.

-The UE receives the NZP CSI-RS resource set IE including the RRC parameter for'repetition' from the BS through RRC signaling. Here, the RRC parameter'repetition' is set to'ON'.

-The UE repeats signals on the resource(s) in the CSI-RS resource set in which the RRC parameter'repetition' is set to'ON' in different OFDM symbols through the same Tx beam (or DL spatial domain transmission filter) of the BS Receive.

-The UE determines its own Rx beam.

-The UE omits CSI reporting. That is, the UE may omit CSI reporting when the shopping price RRC parameter'repetition' is set to'ON'.

Next, a process of determining the Tx beam of the BS will be described.

-The UE receives the NZP CSI-RS resource set IE including the RRC parameter for'repetition' from the BS through RRC signaling. Here, the RRC parameter'repetition' is set to'OFF', and is related to the Tx beam sweeping process of the BS.

-The UE receives signals on resources in the CSI-RS resource set in which the RRC parameter'repetition' is set to'OFF' through different Tx beams (DL spatial domain transmission filters) of the BS.

-The UE selects (or determines) the best beam.

-The UE reports the ID (eg, CRI) and related quality information (eg, RSRP) for the selected beam to the BS. That is, when the CSI-RS is transmitted for the BM, the UE reports the CRI and the RSRP for it to the BS.

Next, a UL BM process using SRS will be described.

-The UE receives RRC signaling (eg, SRS-Config IE) including a usage parameter set to'beam management' (RRC parameter) from the BS. SRS-Config IE is used for SRS transmission configuration. The SRS-Config IE includes a list of SRS-Resources and a list of SRS-ResourceSets. Each SRS resource set means a set of SRS-resources.

-The UE determines Tx beamforming for the SRS resource to be transmitted based on the SRS-SpatialRelation Info included in the SRS-Config IE. Here, the SRS-SpatialRelation Info is set for each SRS resource, and indicates whether to apply the same beamforming as the beamforming used in SSB, CSI-RS or SRS for each SRS resource.

-If SRS-SpatialRelationInfo is set in the SRS resource, the same beamforming as the beamforming used in SSB, CSI-RS or SRS is applied and transmitted. However, if SRS-SpatialRelationInfo is not set in the SRS resource, the UE randomly determines Tx beamforming and transmits the SRS through the determined Tx beamforming.

Next, a beam failure recovery (BFR) process will be described.

In a beamformed system, Radio Link Failure (RLF) may frequently occur due to rotation, movement, or beamforming blockage of the UE. Therefore, BFR is supported in NR to prevent frequent RLF from occurring. BFR is similar to the radio link failure recovery process, and may be supported when the UE knows the new candidate beam(s). For beam failure detection, the BS sets beam failure detection reference signals to the UE, and the UE sets the number of beam failure indications from the physical layer of the UE within a period set by RRC signaling of the BS. When a threshold set by RRC signaling is reached, a beam failure is declared. After the beam failure is detected, the UE triggers beam failure recovery by initiating a random access procedure on the PCell; Beam failure recovery is performed by selecting a suitable beam (if the BS has provided dedicated random access resources for certain beams, these are prioritized by the UE). Upon completion of the random access procedure, it is considered that the beam failure recovery is complete.

D. URLLC (Ultra-Reliable and Low Latency Communication)

URLLC transmission as defined by NR is (1) relatively low traffic size, (2) relatively low arrival rate, (3) extremely low latency requirement (e.g. 0.5, 1ms), (4) It may mean a relatively short transmission duration (eg, 2 OFDM symbols), and (5) transmission of an urgent service/message. In the case of UL, transmission for a specific type of traffic (e.g., URLLC) must be multiplexed with another transmission (e.g., eMBB) scheduled in advance in order to satisfy a more stringent latency requirement. Needs to be. In this regard, as one method, information that a specific resource will be preempted is given to the previously scheduled UE, and the URLLC UE uses the corresponding resource for UL transmission.

In the case of NR, dynamic resource sharing between eMBB and URLLC is supported. eMBB and URLLC services can be scheduled on non-overlapping time/frequency resources, and URLLC transmission can occur on resources scheduled for ongoing eMBB traffic. The eMBB UE may not be able to know whether the PDSCH transmission of the corresponding UE is partially punctured, and the UE may not be able to decode the PDSCH due to corrupted coded bits. In consideration of this point, the NR provides a preemption indication. The preemption indication may be referred to as an interrupted transmission indication.

Regarding the preemption indication, the UE receives the DownlinkPreemption IE through RRC signaling from the BS. When the UE is provided with the DownlinkPreemption IE, the UE is configured with the INT-RNTI provided by the parameter int-RNTI in the DownlinkPreemption IE for monitoring of the PDCCH carrying DCI format 2_1. The UE is additionally configured with a set of serving cells by INT-ConfigurationPerServing Cell including a set of serving cell indexes provided by servingCellID and a corresponding set of positions for fields in DCI format 2_1 by positionInDCI, and dci-PayloadSize It is set with the information payload size for DCI format 2_1 by and is set with the indication granularity of time-frequency resources by timeFrequencySect.

The UE receives DCI format 2_1 from the BS based on the DownlinkPreemption IE.

When the UE detects the DCI format 2_1 for the serving cell in the set set of serving cells, the UE is the DCI format among the set of PRBs and symbols of the monitoring period immediately preceding the monitoring period to which the DCI format 2_1 belongs. It may be assumed that there is no transmission to the UE in the PRBs and symbols indicated by 2_1. For example, the UE considers that the signal in the time-frequency resource indicated by the preemption is not a DL transmission scheduled to it, and decodes data based on the signals received in the remaining resource regions.

E. mMTC (massive MTC)

Massive Machine Type Communication (mMTC) is one of 5G scenarios to support hyper-connection services that communicate with a large number of UEs at the same time. In this environment, the UE communicates intermittently with a very low transmission rate and mobility. Therefore, mMTC aims at how long the UE can be driven at a low cost for a long time. Regarding mMTC technology, 3GPP deals with MTC and NB (NarrowBand)-IoT.

The mMTC technology has features such as repetitive transmission of PDCCH, PUCCH, physical downlink shared channel (PDSCH), and PUSCH, frequency hopping, retuning, and guard period.

That is, a PUSCH (or PUCCH (especially, long PUCCH) or PRACH) including specific information and a PDSCH (or PDCCH) including a response to specific information are repeatedly transmitted. Repetitive transmission is performed through frequency hopping, and for repetitive transmission, (RF) retuning is performed in a guard period from a first frequency resource to a second frequency resource, and specific information And a response to specific information may be transmitted/received through a narrowband (ex. 6 resource block (RB) or 1 RB).

F. AI basic operation using 5G communication

3 shows an example of a basic operation of a user terminal and a 5G network in a 5G communication system.

The UE transmits specific information transmission to the 5G network (S1). And, the 5G network performs 5G processing on the specific information (S2). Here, the 5G processing may include AI processing. Then, the 5G network transmits a response including the AI processing result to the UE (S3).

G. Application operation between user terminal and 5G network in 5G communication system

Hereinafter, an AI operation using 5G communication will be described in more detail with reference to Salpin wireless communication technologies (BM procedure, URLLC, Mmtc, etc.) prior to FIGS. 1 and 2.

First, a basic procedure of an application operation to which the eMBB technology of 5G communication is applied and the method proposed in the present specification to be described later will be described.

As in steps S1 and S3 of FIG. 3, in order for the UE to transmit/receive signals, information, and the like with the 5G network, the UE performs an initial access procedure and random access with the 5G network prior to step S1 of FIG. 3. random access) procedure.

More specifically, the UE performs an initial access procedure with the 5G network based on the SSB to obtain DL synchronization and system information. In the initial access procedure, a beam management (BM) process and a beam failure recovery process may be added, and a QCL (quasi-co location) relationship in the process of receiving a signal from the 5G network by the UE Can be added.

In addition, the UE performs a random access procedure with the 5G network for UL synchronization acquisition and/or UL transmission. In addition, the 5G network may transmit a UL grant for scheduling transmission of specific information to the UE. Therefore, the UE transmits specific information to the 5G network based on the UL grant.

11 is a view for explaining a method of detecting an article unsuitable for the use of an oven according to various embodiments of the present specification.

11 illustrates a case in which a spoon I1c and a bread I2c are provided in the oven. Since the oven 13 is generally used for storing food products, the spoon I1c and the bread I2c may be classified as items that do not meet the purpose of the oven 13.

In response to the oven door being closed, the oven 13 may generate an image of an item located inside the oven through a camera.

The oven 13 may classify whether any one of the at least one or more items included in the image belongs to an item group suitable for the purpose of the oven 13 or belongs to an item group not suitable for the purpose of the oven 13. have.

When the oven 13 is classified as an item suitable for the purpose of the oven 13, the generated image may be updated in a database of items suitable for the purpose of the oven 13. When the oven 13 is classified as an item that does not meet the purpose of the oven 13, the generated image may be updated in a database of items that do not meet the purpose of the oven 13.

In particular, when an item included in the image is classified as an item that does not meet the purpose of the oven 13, the oven 13 may transmit a guide message to the user terminal UE1.

Upon receiving the guidance message, the user terminal UE1 may display an image of an item that does not meet the purpose of the oven 13 and the electronic device UE2 in which the image is generated through the display.

For example, the user terminal UE1 may display the text'There is a spoon in the oven' through the display because the spoon I1c is an item that does not match the purpose of the oven 13.

As an example, the user terminal UE1 displays, and the bread I2c is an item suitable for the main purpose of the oven 13, so'there is bread in the oven.' Or,'There is bread in the oven. You can display the text “Save in the oven?”. In the case of bread, the bread may be stored in either the database of the first item group or the database of the second item group according to the content of the response message received from the user terminal UE1.

As an example, an item suitable for the use of the oven 13 may include flour kneading, food materials that can be cooked by heating, and the like. Items that do not meet the purpose of the oven 13 may include precious metals, flammable materials, and the like.

Referring to FIG. 11, the user terminal UE1 displays spoon information in a first area R1c of the display and bread information in a second area R1c. The first region R1c may include a first sub-region R11c and a second sub-region R12c. The first sub-region R11c includes the image of the spoon I1c, and the second sub-region R12c includes information about the oven in which the image of the spoon I1c is captured.
